Abstract
The utility model discloses a dual-gear oil pump which comprises a shell, a bottom cover, a bearing, a front oil inlet, a rear oil inlet, a bolt and a flange, wherein the shell is made of a high-strength aluminum alloy material; the bearing is arranged in a position of a middle axis of the shell; the bottom cover is arranged at the bottom of the shell; the bolt is arranged on the bottom cover; the flange is arranged on the bearing and is a rhombus-shaped flange; the front oil inlet and the rear oil inlet are arranged in the upper and lower positions on one side of the shell; and during an operation process, the output volume of the front oil inlet is more than the output volume of the rear oil inlet. The dual-gear oil pump has a simple structure; a high-quality steel material is selected, so that the service life of the dual-gear oil pump is prolonged; and according to the more optimized design, in practical use, the dual-gear oil pump has the advantages of low noise, high pressure, high volume efficiency, strong shock resistance, and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, in particular a kind of duplicate gear oil pump.
Background technique
At present, the duplicate gear oil pump in use, according to the difference of flow; Carry out different operation, the more effective energy saving of ability, therefore; Be widely used on the engineering machinery such as fork truck, loader, hoist, road roller, but when operation, can have sent bigger noise; Perhaps vibrations are bigger, and operator's body and mind is affected, and also can influence working life extremely simultaneously.
The model utility content
The purpose of the utility model promptly produces thus, proposes a kind of duplicate gear oil pump, makes it in use have stronger applicability.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme, a kind of duplicate gear oil pump; Comprise housing, bottom, bearing, preceding filler opening, back filler opening, bolt and flange, said housing adopts high-strength aluminum alloy material, thereby improves the working life of himself; The medial axis position of said housing is provided with bearing, and the bottom of said housing is provided with bottom, and said bottom is provided with bolt; Said flange is located on the bearing, and is the rhombus flange, said preceding filler opening and the upper and lower position of back filler opening in a side of housing; And when operation, the discharge capacity of preceding filler opening is greater than the discharge capacity of back filler opening.
The beneficial effect of the utility model: this duplicate gear oil pump simple in structure; The high-quality steel of choosing can prolong its working life; The design of more optimizing simultaneously; In actual use, make it have advantages such as noise is low, pressure is high, volumetric efficiency is high, shock resistance is strong, thereby make it more extensive in practical application.
